To alt Loh/0m it may concern:

Be it known that I, MILTON H. BERRY a citizen of the UnitedStates,residing. in C icago, county ofCook, and State of Illinois, haveinvented certain 'new and useful Im provements in Windovv-Ventilatore.

My invention relates to that class of de- 'vices'which are intended topermit O'I' the raising of a Window Without subjecting the room to adirect draftcaused by the opening.

The invention 'is designed as an improvement upon my invention describedin my application Serial No. 304,611-,'and has for .its Object toprovide means to prevent the Weight of the Window-sash from coming onthe vent the air at the ends of the ventilator, a has for its furtherobject to construct a ventilator which may beused in Pullman or othercars and which will ermit of the ventilation ofthe car Without t eadmission of dirt, cinders, &c.

My methodof accomplishing the foregoing may be more readily understoodby having reference to the accompanying drawings,

which are Vhereunto annexed and are a part ofl this specification, inWhich- Figure 1 is an elevationof a Window frame and sashhaving myimproved ventilator attached thereto. Fig. 2 is an end elevation of theventilator proper. Fig. 3 is atop view of designed so that it may beattached to thesash of'thewindow and remain attached at all times, itbeing so constructed as tobe au- L tmatically adjusted by thejraising'4and low. 45.

In Fig. 4theventilator is s hown attached tothe sash 3,' although 1t 1s obvlous'thatit may be attached to-either theupper orlower sash. vIt is' constructed,as` v better seen'in the detailed view of Fig. 2,' of a i top and bottom5 and 6, the top 5-be1ng provided With a large number ofminuteperfospecification of Lettere Patent.

One of the difficulties of providing a venti- -lator adapted to open andclose with the opening and-.closing of a window is caused by the factthat if the Window is raised to a height equally to the two sides 7 and8 they windowisclosed they must, either be ushed inwardly or are liableto be broken ythe pressure exerted onthe sash. I prevent this y means ofstops 14, which are composed of two members 15 and 16, which areattached to the top and bottom ofthe ventilator by pins or pivots 1 7 attheir extremities. These strips are pivotally attached to each other bymeansv ofy a pin or pivot 18. The upper member 14' is further providedwith a -shoulder .19', this shoulder being adapted to vmembers7 and 8'into the position shown in Fig. 2 thevshoulder on the member I15 pre-Will assume a vertical position, and when the oq engage` the member 16.as the windoW -is I r raised, with the result that when thewin- .V dowhas been Open suiliciently to bring the ventslits openngany farther byengaging v the .member` 16.v The result-is that the memsition,Land-conse u ently it is impossible-for them to be in suc a position asto'be Asubore being'in position to close with the win# OW, v Y: 4Vlherethe ventilator is to be used in trai-ns.

l With the said sash, its inner Wal top 5 and covering the pei'forationstherein, the mesh of the screen being small' enough to prevent/"theadmission of cinders Without excluding the air. When the window israised and it is desired to close the openings a-t `the end, themetalstrip 11 may be inserted in the slot 10 and will then assume theposition shown in Fig. 2, in which it is apparent that all the end isclosed with the exception of a small portion at the pointof unionbetween the members 7 and 8 and the to and bottom, respectively. Whenthe win( ow is closed, the strip 11 is automatically ejected from theslot 10 and assumes the position shown in Fig. 3.-

An inspection of the drawings discloses the fact that the ventilator isto be at` all times on the interior of the window and when closed; asshown in Fig. 7, lies entirely within the-Window, and is consequentlyeasy to get at at any) and all times. The members 7 and 8 may e providedwith glass panels, if a transparent ventilator is desired, or they ma beformed of metal plates.

aving described my invention, what I regard as new, and desire to secureby Letters Patent, is-

1. The combination With a window'having m'ovable sashes, of a ventilatoradapted to open and close with the o ening and closing o thewindow-sash, sai ventilator being foldable and having. a horizontalperforated plate attached to the sash, the whole ventiatorsetting insideof the sash, said horizontal perforated plate being covered with a finescreen, for the purpose set forth, substantially as described.
